DETERMINE RISKS OF CROSSING

Risks exist as follows:

At signals:

there are risks from:
- parallel traffic turning right into the crosswalk;
- parallel traffic turning left into the crosswalk;
- perpendicular traffic turning right-on-red across the crosswalk;
- perpendicular traffic running the red light.

At uncontrolled crossings:

if intending to cross during a gap in traffic and
- you are able to hear/see all traffic far enough to know when it's clear to cross, the risk is ...
  ... negligible;
- you are at a situation of uncertainty for gap judgment, there are risks that ...
  ... as you start to cross, undetected vehicles are approaching that can reach you during the crossing;
if intending to rely on drivers to see and avoid you, there are risks that ...
... drivers will fail to stop or yield.

At two-way stop signs (crossing the street with the stop sign):

there are risks from
- parallel traffic turning left or right into the crosswalk;
- perpendicular traffic approaching or waiting at stop sign; and
- traffic from the stop sign across the street.

At four-way stop signs:

there are risks from
- stopped cars that surge forward and cross your path from any direction;
- if intending to cross when no traffic is present, there are risks from idling vehicles that you can’t hear or see.

NOTE: For people who are unable to see or hear the traffic, assistance is needed to observe / evaluate the situation.
